“The Syrians braced themselves for the Israeli onslaught. “Pave the roads with the skulls of Jews,” Assad ordered. “Strike them without mercy.” The fight, Damascus held, was not over.”
Once Dayan decided against a limited attack in the Golan and opted instead to take the entire Heights, Israel’s air force pounded the Syrians. The Syrians had supposed the Israelis to be tired and intimidated by their incessant shelling; unprepared for the ferocity of the barrage, their morale suffered, and some officers and soldiers deserted. But the bulk of Syria’s forces remained in place, ready to give fight, while hoping for UN intervention.
Traffic jams delayed Israeli reinforcements from other fronts, retarding an assault from the south; the attack proceeded in the center, but involved exhausted Israeli tank crews climbing the rocky terrain of steep (2000 ft) hills in broad daylight, totally exposed to Syrian fire from the enemy’s most formidable forces. Upon hearing of the plan, some commanders described it as “suicide.” But they proceeded unafraid.

With tank maneuverability reduced by the terrain, the Israelis found themselves at the mercy of dug-in Syrian tanks. Pressing on, the fighting was intense and confused as tanks fired at extremely close range. Maps were lost, bulldozers were destroyed as they tried to clear away barbed wire, and the threat of landmines was everywhere. The Israelis also underestimated the ability of the Syrian bunkers to withstand massive bombing.
“The Syrians fought well and bloodied us,” recalled one Israeli commander, but after a whole afternoon in battle, the IDF had made important advances. The successes were not without cost, however, in men and arms. The Syrians did manage to stop the IDF’s movement, but they too had taken a beating, and were left fearful and chaotic.
